Any body actually dyno tested these parts? high flow elbow plus 75mm thotle body? BBK claims 11-15hp, but im wondering if anyone has some actual numbers???

 

THe throttle body alone will give you maybe 2 hp to the wheels. Not sure what you mean by elbow, but if you're taking about a CAI then that could give you about 5 rwhp.

 

I think he means plenum from the New Era vendor post.

It'll get you about 6-8rwhp if you already have a CAI.

Not to criticise the vendors, but give them a call and see exactly what brand of plenum it is.

 

Here you go my friend:

thats wierd. the dynos claim that the 75mm accufab and plenium make less hp that the 70mm combo? that seems strange to me

 

Hard to tell. In the article, when they did the 75 MM, the basline with OEM TB/Plenum had more HP/TQ so the GAIN showed up smaller on the 75mm for some reason but the total PEAK was still more with the 75MM. Now we should try to get these two runs on the SAME graph so that we can see if the 75mm gave up any low-end TQ/HP and if the 75MM maybe only shines at high RPM. Anybody good with images?

70 MM: 264.61 RWHP 297.03 RWTQ Gains: 7.94 RWHP 7.6 RWTQ

75 MM: 272.38 RWHP 310.42 RWTQ Gains: 6.31 RWHP 6.88 RWTQ
